PATENT OFFMIE.

HERMAN C. BUSCI-I, OF DENVER, COLORADO.

BROKEN-LENS GAP.

Application filed October 4, 19 22.

To all whom it may concern.

Be it known that I, HERMAN O. Boson, a citizen of the United States, residing at Denver, in the city and county of Denver and State of Colorado, have invented new and useful Improvements in Broken-Lens Caps, of which the following is a specification.

It frequently happens in the use of eyeglasses that a lens is broken at and adjacent to the point where the lens is connected to a nose piece.

The object of my invention is the provision of a cap adapted to hold a lens broken in the manner indicated and to contribute to the strong connection of the said lens to a nose piece so that the waste involved in throwing the lens away is obviated.

To the attainment of the foregoing, the invention consists in the improvements as hereinafter described and definitely claim ed.

In the accompanying drawings, forming part of this specification Figure 1 is a front elevation of a pair of eyeglasses embodying two of my novel holders.

Figure 2 is a detail horizontal section taken in the plane indicated by the line 2-2 of Figure 1.

Figure 3 is a detail view showing a broken lens and the manner of associating my novel holder therewith.

Figure 4: is an enlarged perspective of one of my novel holders per se.

Qimilar numerals of reference designate corresponding parts in all of the views of the drawings.

The pair of eyeglasses shown in Figure 1 comprises a nose piece 1 with nose clips 2. It is to be understood, however, that my in vention is not restricted to eyeglasses of the pince-nez type inasmuch as it is equally applicable to other types of eyeglasses.

Lenses broken at points 3 are designated by at, and my novel lens holders are designated by 5. The said lens holders 5 are formed of appropriate metal and are characterized by side walls 6 and end walls 7, the end walls being curved in conformity to the edges of the lenses after the manner best shown in Figure 3. The side walls 6 of the holders are apertured as indicated by 8 to receive threaded bolts 9 through the medium of which the holders are connected to coupling links 10 and 11. attached to the nose piece 1 Seriafl No. 592,209.

in the manner illustrated or in any other appropriate manner. At 6 the side walls of the holders are provided with indentures to receive and snugly seat protuberances 7 X on the links 10 and 11. These features 6 and 7 are of the essence of my invention inasmuch as they contribute materially to the lens retaining capacity of the holders; the holders 6 and their links 10 and 11 being interlocked, and the bolts 9 by cooperation with the links and the side walls of the holders 6 being adapted to strongly clamp a lens without liability of the lens working loose. The links 11 are provided with threaded apertures 12, Figure 2, and from this it follows that when the parts are relatively arranged as shown in Figure 2 the holders will be strongly clamped on the lens so as to securely hold the lens notwithstanding the part broken out of the lens as indicated by 3, in Figure 3.

It will be manifest from the foregoing that through the medium of my novel holders the necessity of replacing lenses broken in the manner described with new lenses is obviated. It will also be manifest that my novel holders may be associated with any appropriate couplings that embody means for clamping the holders against the lenses and that the holders do not interfere in any measure whatever with the vision of the wearer of the pair of eyeglasses embodying my improvement.

I would further have it understood that my novel holders are adapted to be used in combination with new lenses in which event the holders will serve to materially lessen the liability of glasses being broken as indicated by 3 in I igure 3 when the glasses are dropped.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts inasmuch as in the future practice of the invention various changes and modifications may be made such as fall within the scope of my invention as defined in my appended claim.

Having described my invention, What I claim and desire to secure by Letters Patent, 1s:-

A device of the character described comprising an arcuate channel-shaped member adapted to embrace one edge of an eye glass lens and havlng a transverse notch, arms adapted to be connected with the nose piece HER-MAN C. BUSH-1.
